5万吨级前置预旋导轮结构设计及强度直接计算方法研究

摘要

There are no specified requirements available for the strength of Pre-Shrouded Vanes (PSV) and its accessories. In this paper, a 50K DWT bulk carrier’s PSV structure is taken for the research object. The simulation based design method is adopted for the PSV structure. According to calculation result the original structure is optimized. The PSV product has been manufactured and installed at the ship. The method of the PSV strength design proposed in this paper is satisfied for engineering application, and can be applied to the similar structure design.%目前各大船级社还没有针对前置预旋导轮及附属结构的明确的设计规范或规定。论文以一艘5万吨级散货船的前置预旋导轮为研究对象，采用有限元直接计算方法对导轮结构进行强度分析。对设计的结构进行了振动计算和强度校核。根据计算结果对结构进行了加强，形成的产品已经安装到实船。论文提出的导轮结构强度设计计算方法能满足工程应用需要，还可应用于同类产品的结构设计。
